Determinations of the permeability coefficient for water show that the osmotic behavior of amphibian eggs (ovarian and coelomic eggs from Rana temporaria) cannot be accounted for by this factor alone. Comparison of the cortical stiffness of coelomic eggs with vitelline membrane i n iso-and hypotonic
The water exchange has been measured in oocytes of Siredon mexicanum and Rana temporaria, and in unfertilized eggs and early gastrulae of the former species, by recording the D20-H20 exchange with the Cartesian diver balance. In oocytes, where no diffusion barrier to water is demonstrable, the temp
The motion of the ovum and the spermatozoa toward each other in the oviduct culminates in a meeting that ultimately results in fertilization. This encounter is characterized by a slow rotation of the sperms}egg cluster while the sperms attempt a penetration. The mysterious rotation was observed in v
